SPECIFICATION forming part of Letters Patent N o.. 567,833, datedSeptember 15, 1896. Application led December 12, 1895l `Serial No.571,930. (No model.)

To CLZZ whom t may concern:

Be it known that I, JOHN KIRBY, Jr., a citizen of the United States,residing at Dayton,county of Montgomery, and State of Ohio, haveinvented certain new and useful Improvements in Lamps, of which thefollowing is a specification.

My invention relates to lamps, more particularly to the class of hanginglamps used in railroad-cars, steamboats, and the like; and it has forits object an improved form of construction, whereby a plurality ofreservoirs supplying oil to a single burner are detachably supported byarms branching from a central hanger or frame, and by which construction-a light, rigid, compact, and handsome lamp is obtained.

The invention consists of a hollow central supporting hanger or frame,through which and a ventilator communicating therewith the products ofcombustion escape to the outer atmosphere, the lower end of which hangeris adapted to receive and carry a shade above the burner, in properrelation thereto, and is provided with branching arms carrying aplurality of detachable reservoirs,which communicate with acentrally-located burner, together with certain other novel features ofconstruction, as shown in the accompanying drawings, and which will bemore fully hereinafter described, and then pointed out in the claims.

Similar letters and gures of reference indicate corresponding parts inthe several iigures of the drawings, in which- Figure lis a sideelevation of the lamp and its ventilator in partial section. Fig. 2 is aside elevation of the lamp with the reservoirs and burner detached. Fig.3 is a perspective view of the smokeflue and its support detached fromthe hanger. Fig. 4 is a perspective view of the shade-holder.

A represents a carceiling,and B the roof.

C is a hollow cylindrical hanger or frame (hereinafter designated hangerwith an enlarged base 4for rigid attachment to the ceiling, and providedwith suitable openings c1, through which heated air in the vicinity ofthe lamp can escape to the outer atmosphere through a ventilator D,securedxin the roof and ceiling, and as indicated by arrows l, 2, andThe lower end of this hanger is provided with armsE F,extendingoutwardly and downwardly, and on their lower ends are formed couplings 67, preferably in the shape of tapering sleeves, as shown.

G I-I are storagefreservoirs provided with tapering pins I J, which areadapted to enter the sleeves on the arm and support the reservoirs andburner in position. Midway between these storage-reservoirs is mounted aburner-reservoir K, having aburner L anda drip-cup M. Hollow arms N Oconnect the reservoirs G, H, and K and convey oil from I the former tothe latter in the same manner as in the well-known student-lamp,` whichform I consider best for the purpose of carrying out my invention.

In the lower end of the hanger C is secured a hollow cylindricalscrew-threaded smokeflue support P, preferably made of sheet metal, towhich is joined at b a conical-shaped smoke-flue Q, above which ismounted a cap R,supported by metal strips c, to prevent downward draftsof air entering the chimney S. The interior of the flue Q is preferablylined with some suitable non-conducting fireproof material, such asasbestos, to protect the line from heat, as indicated by the letterT,the products of combustion passing through the ventilator, asindicated by arrows 4, 5, and 2.

It will b'e noticed that the exit end of the flue is above the openingsa in the hanger, and also that the lower end of the ventilator is belowthe eXit end of the flue and slightly within the upper end of thehanger. By this construction and arrangement an upward current will beinduced by the hot air in the vicinity of the lamp passing into thehanger through its openings, and this current will carry upward andoutward with it the products of combustion issuing from the smokeflue. Ashade Uis held above and in proper relation to the burner by means of aflanged annular screw-threaded shade-holder Y, the latter passingthrough the neck of the shade until the flange bears against theinterior thereof and then screwing into the smoke-flue support, as shownclearly` in Fig. 1;

What I claim as my invention, and desire to secure by Letters Patent,is-

IOO

l. In a lamp, the combination with a hollow central hanger adapted to besecured to a cancelling or other overhead support and provided at itslower end with a plurality of outwardly and downwardly hanging,` arms,of a plurality of storage-reservoirs in eo1n1nunication with aCentrally-arranged burner-reservoir, and means for coupling therespective storage-reservoirs directly to the lower ends of said arms.

2. In a lainp, the combination7 with a hollow Central hanger adapted tobe secured to a oar-ceiling or other overhead structure, and a centralburner below and in line with the hanger and provided with a chimney, ofa smoke-line support secured in the lower end of the hanger and carryinga s1noke-iiue, a

shade-holder removably secured in the smokeflue support, and a shadeheld in Contact with the lower end of the hanger by said holder.

In a lamp, the combination, with a hollow Central hanger, of asmoke-flue therein, an annular support for said flue secured in thelower end of the hanger, a shade, and a langed annular shade-holderadapted to be passed through the neek of the shade until the flangeengages with the interior thereof and to be removably secured in thesmokeiiue support.
